MAIL DELIVERY AND RECEIVING DEVICE'.

Specification of Letters Patent.

Fatented Dec. 21,- 1920.

Application :filed September 15. 1919. Serial No. 323,967.

To all whom it may concern:

Be 1t known that I, ROBERT LEMMER, a

citizen of the United States, and a resident of Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Mail Delivery and Receiving Devices, of which the following is a specification.

The general object of this invention is to provide an improved form of mail delivery device whereby mail may be delivered safely and economically from fast moving trains, and deposited in a suitable receptacle provided for the purpose.

One object of my device is to provide mechanism Carried by the mail car that can be readily swung from an operative position on the exterior of the car to an inoperative and locked position on the interior `of the car. p

Another object is to provide in the car an improved type of mechanism for safely holding a mail sack in the device until the actual point of delivery is reached, and at the same time will readily deliver the mail sack when called vupon t0 do so.

Another object is to provide a mail receiving mechanism havingtherein means for tripping the car delivery device, having also means for taking up the shock of the delivery and having means for receiving the delivered mail into a suitable mail receptacle.

With these and incidental objects in view,

the invention consists ofcertain novel fearel 6 to allow the easy passage therethrough tures of construction and combination of parts, the essential elements of which are hereinafter described with reference to the drawings which accompany and form a part of, this specification.

In the drawing, Figure 1 is a plan view of a portion of a carv wall showing the delivery. device mounted thereon, and showing the delivery device in dotted lines Ain two positions in the interior of the car;` Fig. 2 is a front view of the mail delivery device as seen from the interior of the car; Fig. Sis a side elevation of the delivery barrel; Fig. 4 isan end view of the same; Fig. 5 is a section taken on the line 5 5, Fig. 6; and Fig. 6 is a plan view of the mail receiving device.

Mounted on the wall 1, Fig. 1, of the car is a bracket 2 having a turn table 3 mounted thereon. Hinged to the turn table at 4 is an arm 5 carrying a barrel 6.

By swinging' the arm 5 in a. clockwise direction, as shown in Fig. 1, the barrel 6 will swing in through the car door at 7, to the position shown dotted at 8.

Byswinging the arm 5 upwardly about its hinged point 4 the barrel 6 may be .brought to the position shown dotted at 9, which is its normal riding position.

Lugs 10 on the turn table 3 serve to steady the arm 5 when it is riding in its outer or delivery position.

vMounted at 11, Fig. 3, is a bell crank one end 12 of which serves as a triggenand the other end 13 of which is hinged at 14 to the link 15, which has its other end hinged at 16 to the link 17, hinged at 18 and carrying the closure 19.

nThe mail sack that is to be 4delivered is placed in the barrel 6 while it is inside of the car, and the delivery device is then swung to the outside of the car to the position shown in full lines in Fig. 1, and it will be apparent that neither wind pressure nor jolts received from the mail sack on the closure 19 can open that closure, because of the relative position of the hinged points 11, 14, and 16, but that if the trigger 12 is rotated in a counter clockwise direction, closure 19 will be opened so as to allow the mail sack to be readily delivered through that end of the barrel 6. y

A slot 2O runs longitudinally of the barof means provided in the receiving mechalnism for working the trigger 12 and removing the mail sack from the barrel 6. Looking no w at the mail receiving mechanism, shown in Figs. 5 and 6, it will be seen that this comprises essentially a receptacle 21`havin`g hinged to the walls 22 at 23 a tiltalole fram-e 24 carrying at. one end a bumper 25. Slidably mounted with respect to the receptacle 21 is a shaft 26 and a spring 27; and a set collar 28 normally holds this shaft in a position extending toward the right. head 29 is provided on one end of the shaft, which may strike the fixed collar 30 at the extremeleft hand position of the shaft so as to limit the possible motion of the shaft.

Hinged at 31 on the lug 32, carried by the y tionof a bracket adapted to be mounted on shaft 26, is a link 33, the other end of which is hinged at 34 to one arm 35, of a bell crank hinged at 36, the other end of the bell crank 37 normally holding the end 38 of the frame 24, which by gravity or other suitable means is adapted to rest against the end 37 of the bell crank. Y

Hinged at 39 in the receptacle walls is a trap door 40, which by the counterweight 41 is normally held in a closed positionl againstV the stops 42, carried by the walls of the receptacle. Y

Suitably mounted on shaft 26 is a delivl ery disk 43 of such size as to freely pass .through the barrel 6 with suitable allowances mail sack itself and the mail sack will be.

swept outof the barrel 6 before the closure '19 would have time to resume its closed position through its own weight. Y The spring 27 takes up the jolt of the impact against the mail sack and, after the sack has lostdits momentum and the train has passed, throws the sack to the right.

When the disk 43 was moved to the left by the impact of the mail sack, the'link 33 and bell crank swung the end 38 ofthe frame 24 downwardly, thereby lifting the bumper 25 against which the mail sack is thrown by the `return of the disk 43. i

.The'mai'l sack falls on the trap door 40 and its weight overcoming the balance of the counterweight 41, the Vmail sack drops below the trap door` through the framework 24 and falls onk the bottom of the receptacle from where itis taken by the mail clerks.- Y While I have -described my invention and illustrated it in one particular design, I `do ynot wish it understood that I limit `myself to this construction, as it isk evident that the application of the invention may be varied inmany ways within the scope of the following 'claims j l. In a mail delivery device, the combina- Lthe wall of a mail car and adjacent to the deliverybarrel vcarried by said arm, a closure for-one end of said barrel, and means operable vfrom `the exterior of said car for 'open- 1,362,soe

ing said closure so mail may be delivered from the closure end of said barrel.

2. In a mail delivery device the combination with a turn table of an arm hinged thereto, a delivery barrel carried by said arm and having both endsthereof open, a closure hinged to one end of said barrel and adapted 'to close said end, said barrel having a longitudinal slot throughout the wall thereof.

3. In a mail receiving device the combination of a receptacle, a delivery disk slidably mountedwith respect to said receptacle, a spring cushion for taking up impacts delivered against said disk, a bumper mounted to be swung into a receiving position in frontY of said delivery disk by the movement of said disk, under impact receivedthereby, whereby an object striking said disk may be thrown by said disk against said bumper.

4. In a mail receiving device the combination with a receptacle of a shaft slidably mounted thereon, a delivery disk carried by said shaft, a spring cushion associated with said shaft to take up impacts delivered against said delivery disk, a swingable bumper actuated by slidable movement of said shaft, and a hinged trap door positioned in frontof said bumper and adapted to receive thereon an object thrown from said Vdisk and allow said object to pass by said trap vdoor into that portion of the receptacle below said trap door.

In a mail delivery and receivingdevice the combination of a delivery device comprising a delivery barrel having free passageway therethrough, but having a hinged closure mounted at one end thereof, means for locking said closure in its closed position, means positioned in the opposite end of said barrel vfor opening said closure, and a re- Y ceiving device comprising in combination a receptacle, a delivery disk for actuating said closure opening means and sweeping mail matter positioned in said barrel therefrom.

6. In a mail delivery and `receiving device the combination of a delivery `device comprisingV a delivery barrel having free passageway therethrough, but having a hinged closuremounted at one end thereof, means for locking said closure in its closed' position, means positioned in the. opposite end of said barrel for opening said closure, and

a receiving device comprising in combination a receptacle, aldelivery disk for actuating said closure opening means and sweeping mail matter positioned in :said'barre'l therefrom, and means including a trap door for receiving mail from said Vdelivery disk past said trap door and to a receptacle positioned below.
